Abstract: In the practice of sensor measurements making sense of numerical information becomes an important factor in the usability of the sensor itself. Typical sensors output a given voltage or current as a direct relationship to the load. This load can be force, torque, pressure or temperature. The outputs given by sensors are typically raw numerical information. This information is typically useless and must be converted to a standard engineering unit. Once this conversion takes place we can start making sense of how these forces interact in a system under test. These raw voltages can be also ratiometric, meaning that output is proportionally affected by excitation voltage. Outputs can also be absolute, meaning they are not dependent on excitation voltages.
Keywords: IEEE 1451.4 standard, Output, Sensor measurements, Ratiometric, Plug and play
